I think honesty is the keyword in all.
Honest to yourself: why are you joining a forum?
But also honesty to the posters= real people on the forum. Don't cultivate a picture of yourself that's not you.
Also honesty to your partner: my husband knows and can read over my shoulder if he wants. I sent the 1000-post celebration-thread as a link to him; to let him share in the fun LCJ and I had thinking the business of celebrating up.
I also think Beppe is honest in trying to define for himself where he wants to go and to ask on the forum to explore this subject a bit more.
